Mock Exam similar to actually test?

So I was just wondering for level II if the mock exam is very similar such as level 1?

Level 1 if you had a strong understanding of the mock exam you could get like 40-50% of the actual test because a lot of the questions were similar with different wording and numbers.

I wasn’t sure if the mock exam for level 2 provided that same comparison or is as important as it is for level 1.

Totally not the case for level 2
